Filtering two IBTable and insert or edit IBTable

[danten]

Hey, they face a new problem of filtering.
I still have the error.
Use components IBTable and join the Firebird database.
I need to filter by date.
My code:tab_attendant.Filter := 'select * from ATTENDANT where "WHEN" >= '+QuotedStr('17.2.2014 00:00:00')+' and "WHEN" < '+QuotedStr('20.2.2014 00:00:00');
